Carolina actually ran a nice play that gained some yardage in the third quarter -- on a fake punt.
On fourth-and-4 from their own 40, Carolina lined up as if to punt but quick-snapped the ball to reserve linebacker Jordan Senn, who barely stretched for the necessary yardage.
This brought a huge cheer from the remaining fans (and there are a surprising number of them left).
Alas for the Panthers, they then got a 27-yard pass to Steve Smith (Jimmy Clausen's first really good throw of the game) negated due to a seriously wrong offensive pass interference call on Smith. That put Carolina in first-and-20, and you know they aren't making that.
So, eventually, they punted for real.
